The Arms Tech USR Prototype

[threefeathers]

This is a pic of the new Arms Tech Urban Support Rifle. It is a Gas Trap, (January 06 SWAT had a good report) 1-9 progressive and polygon rifling. This one has the Crane buttstock. I put GG&G sling things and the Steyr sling on it so I can use the sling when shooting prone. It has a full POF rail system that is very tight. http://i4.photobucket.com/albums/y119/threefeathers/P8110009.jpg

Are they still claiming the super velocity boost with the progressive rifling?

As soon as the rain stops I'll chrono both this one and a 6920 and compare. I do think Joe is correct that there is less wobble to the bullet and that may be why it handles the 77 grain bullet quite well.
Here is a quick shoot last week as I was trying to beat the rain. (I could have gone to the range in the morning but I took my 16 month old grand daughter to breakfast:cool: )

This is the Hunting Shack 77 grain bullet. Rachel sent me 50 to experiment with. Tomorrow I'm going to use the Hronady TAP black cased bullet. It is a hundred fps slower so I hope it cycles this tight chamber. The gas trap takes a hot round to cycle. It is perfect with all military ammo I've used and did the 10,000 round test with M-193.

I'm very pleased with the HST bullets!!!!
